Meet the Houston Team Behind Brennan Roofing Co Houston
We’re a local Houston crew, not a call center. The people who answer the phone and the people who climb the ladder are the same team you’ll see again if you ever need us back. We’re bound by one thing: The Garrison Standard. That means every roof gets the same process, the same materials discipline, and the same written price before any work starts. Travis Oakley owns this location, and the folks below are the ones doing the work in Houston’s heat, humidity, and hurricane season. They know what this climate does to a roof, because they live here too.
Styles & brands we work with






Our People
Marcus D. – Lead Technician
Marcus has spent 14 years on Houston roofs, and he’s been with Brennan Roofing Co Houston since the location opened. He holds certifications from GAF and CertainTeed, which means he’s trained to install their systems to the exact spec those manufacturers require for a valid warranty. Marcus is the person who walks a roof after a hailstorm and tells you straight whether you have damage or just noise. He’s got a dry sense of humor and a habit of drawing diagrams on scrap paper to show homeowners exactly what he’s seeing up there. If Marcus says a deck needs replacement, he’ll show you the rot with a photo before anyone touches a shingle.
Elena R. – Senior Installer
Elena came to roofing from residential framing, and that background shows in how she handles decking, fascia, and the structural details most people never see. She’s our go-to for complex flashing work around chimneys, skylights, and sidewall transitions, which is where a lot of Houston roofs fail long before the shingles do. Elena is trained on Atlas and Tamko product lines and keeps her fall-protection certifications current without being asked. She’s the one who notices when a drip edge is a half-inch off and fixes it before it becomes a leak. Off the clock, she’s usually restoring an old truck and pretending it’ll be done this year.
DeShawn T. – Service Coordinator
DeShawn is the voice on the phone most Houston homeowners hear first. He’s been coordinating service calls for six years and came to Brennan Roofing from a background in property management, so he understands what insurance adjusters ask for and what documentation you’ll need. DeShawn schedules every inspection, makes sure the written price goes out before any work starts, and keeps the 365-Day Done Right Promise paperwork straight on every job. He’s the one who answers at 2 a.m. when a storm rips through and you need someone to look at your roof before the next rain. Ask him about his crawfish boil recipe; he’ll talk your ear off if you let him.
Jose C. – Apprentice
Jose joined the crew two years ago with no roofing experience and a recommendation from a supplier we trust. He’s earning his way through the ranks under Marcus and Elena, learning tear-off, underlayment installation, and proper nailing patterns before he touches anything unsupervised. Jose handles a lot of the clean-up and material staging, and he’s already trained on IKO and Owens Corning installation basics. What stands out about Jose is that he asks good questions, the kind that show he’s actually thinking about why a roof system works, not just how to install it. He’s also the only person on the crew who can back a trailer into a tight Houston driveway on the first try every time, which is worth more than he knows.
One Standard, Every Job
The four people above and Travis all answer to the same thing: The Garrison Code. It’s a written set of expectations every Garrison Partners location agrees to follow when it joins the family, and it’s the reason a Brennan Roofing job in Houston looks like a Brennan Roofing job anywhere else in Texas. The Code covers how we inspect, how we quote, how we install, and how we handle it when something isn’t right. Every job starts with a written price before any work starts, and every repair or installation carries the 365-Day Done Right Promise in writing for one full year. If a repair fails in that window, we come back at no charge. It’s not a slogan. It’s the agreement, and the whole Houston team signed on to it when they came aboard. Travis Oakley expects it, Marcus and Elena enforce it on the roof, DeShawn documents it, and Jose is learning that the standard isn’t negotiable when the weather tests it, which it will.
